Correct me if I'm wrong, but I doubt United fans would want their team to throw a game so City don't win. All the Utd fans I know want to win every game they're in, but of course they want City to do absolutely nothing. I'm of the opinion that you can't control the outcome of other fixtures, so just hope and pray it goes your way. That's what makes sport interesting. I don't see other teams fans clamouring for their team to lose like our fans do.
I wasn't one of those fans that wanted us to lose to City in 13-14, purely because at the time we were still in with a shout of getting 4th, and I hate losing to City always have. I want Everton to win every game regardless. Do I want the RS to be successful, no, but if they are 1). it's none of my concern because it's not my team so why get invested in it (I'm only interested in the blues, I don't pay any notice to any other team) and 2). who cares, it was proven last season when no other fans really acknowledged their title and they were fuming, which was good.
